Hi. Turns out I identified the root of this problem.
The cause was the "skip-grant-tables" on mysqld.cnf file. I use this so I can bypass a permission error on a fresh installed mysql. I just didn't knew I had to remove it after I changed the admin password. Removed the line and the process followed as intended. I think this issue can be closed.
